' VENDING MACHINE,

Application filed May 19,

i This invention relates to vending ma- 'Cl11I1S, 3.Ilfl has particular reference to a machine which while principally designed for vending cigarettes, is not necessarily restricted to such useand the right is reserved to employ the same for the purpose of vending any other articles of which it is capable.

The invention primarily comprehends a vending machine of the character set forth which 'is' extremely compact and which is of the vending machine.

As a further object, the inventionembodies a coin operated mechanism, by virtue of whicha plurality ofcoins may bejinserte'd in the coin slot, prior to or during the operation of the mechanism, wlth the assurance that the vendee will receive a corresponding number of the articles which are being I I mately on the line 5-5 of Figure 2.

vended.

The invention aims as a still further obje'ct to provide an improved coin slot closing device which includes'means operable to obstruct the coin, slot after apredetermined number of operations of-the coin'operated mechanism, which deviceisfsettable to func- 'tion after the desireclfnumber of operations.

More specifically, the invention comprehends a coin or check operated'mechamsm for successively turninga rotary member a predetermined distance in thesarn'edirec- 'tion, which member es'sentially includes a wary element connected with a the, member to be operated therebyand 'which element intersects a coin guide through whichthe 99 released.

1928, Serial No. 279,074.

Among its objects, the invention resides in the comparative simplicity of construction: and mode of operation of the machine, the economy of its production and assembly andlthe high efficiency and precision with which it operates.

lVith the above recited and other objects in view, reference is had to the following description and accompanying drawings, in which there is exhibited one example or embodiment of the invention, while the claims define the actual scope of the same.

In the drawings-e t Figure l is a front View of the machine.

Referring to the drawings by characters of reference, 10 designatesthe cabinet which is of elongated rectangular configuration and of a depth approximating the length of the cigarettes or other articles to be vended. The

' front wall 11 of the cabinet is removably carried thereby and is secured in place by a suitable lock 12. A suitable partition 13 subdivides the casing or cabinet 10 intovertically "spaced upper and lower compartments 14 and 15, the former constituting a hopper for the reception of the cigarettes C or other articles to 'be vended. The latter compartment is formed with'a delivery trough 16 which coincides with a delivery opening 17 in the lower part of the front wall while said compart- Inent further functions to accommodate a coin box or receptacle 18 for receiving the coins or checks which have been deposited and employed for the purpose of operating the machine. A suitable delivery member 1 9, such as a wheel having circumferentially spaced peripheral notches 20, is mounted for rotation within the partition 13 for receiving 1 the cigarettes or articles from the hopper compartment and for conveying and discharging the same into the delivery trough 16-.

The coin or check operated mechanism which isiemployed Yfor' successively vturning the rotary deliverynmelnber or wheel. 19 is Lhousediin the forwardly offset portion 21 of theZfr'ont; wall andasaid mechanism includes a rotary element 22' which iszkeyed to a shaft '23 which extends axially through andsis se-' curedv tofthe vdelivery member orwheel 19.

The 'el'ement -22 is, as illustrated, in the nature'of a ratchetwheel/having peripheral teeth 24;; One: point of the element o-r'whieel -22: intersects'acoinaguide 2-5:,the upper end of which guide isdisposed: directly under and in line with a coin slot/2 6 formedin the upperdeck. or wall of the ofiset portion 21. The opposite l'ower'en'd of the: coin guide term-i-nates a lipQf? which is disposed: over-the upper open end of? the receptacle 18. A; de-

tent QS' is fulcrumed at 29: and is normally 1 urged by a-spring 3.0 into the'path of moveinentxof. a pri'pheral tooth Qtof the-element or wheel 22, so asto engage with and prevent (turning movement thereof. The detent is also providefdiwith anr 'inclin'ed surface 3'1 '7 which intersects the-coin' guide when thedetent i's'i-n'itsmormal locking engagement with the peripherallteethfofthe elementor wheel 22a *Mounted' embarrass face or thelo'fiset V portion-2'1'ofthetfront wall 11 for limited 3 which worksinthe arcuate'slots 1s. the -platesi3.6'..

In order to provide means for obstructing the coin slot 26after-a predetermined number of operations of the coin mechanism, an obstructing bar 40 is fulcrumed-atl and disposed at a point directly underlying the coin slot 26, a spring Qbeing; employed to swing the'obstructing bar-toa coinv slot obstructing position.v A. gear wheel l3' is journals-d for turning :movement on a stub shaft 44; which projects forwardly from the plate '36, and said gear wheel is removably held'thereon by a cotter pin 45. The teetlrof the .gear' wheel mesh; with the teeth-of a pinion 4K6 wh-iehqis keyed to a shaft 47,130 which a sprocket wheel: 4L8 is secured; The sprocket wheel 418' is rotated in any desired 'manner from and by the ratchetwheel 22, such as by means ofasproeketpinion-49 secured to the shaft 2310f the ratchetwheel and around which sprocket wheel and pinion a sprocket chain 5Qis trained. The gear wheel 43is'pro- 'vided, with an opening or recess 51 while the "coinslot obstructinglbar- 4:0 is provided with a forwardly projecting stud- 52 whichnor- Vmally engages againstthe inner {face of the gear wheel 8 .to'hold-flthebar 40 inan inwardly .movedl position whereit' is out of direct alignment with thecoin slot26. After a predetermined'number of operations of the coin -mechan1sm,. however, the openmg or recess 51 moves to a position, in: registry; with the I stud-N52,;permitting-the spring 42to function 3 to swing; the; obstructing bar 40forwardly to a position directly under. the coin slot 26,

' thereby preventing a: coin from being inserted "in-the slots 25; In order to guide-the person filling thermachine, suitable graduations 54 and-indicia 55am inscribed on the front face; of the gear wheel practice, when "the machine 'has beeni filled" or charged with a certain-number of. cigarettes C, ,the. cotter pin 45is removed and the. gear wheel 43' a coin guide, a rotatably mounted wheel havturned to a position where a corresponding number of operations of the machine will cause the opening or recess 51 to register with the stud 52. In order to provide means for accurately registering the number of cigarettes sold by the machine, a counter 56 may be installed, with which the teeth 24 of the wheel 22 cooperate to actuate the counter up on each operation of the wheel 22. It will be observed that due to the construction of the coin operated mechanism, a plurality of coins may be inserted in the machine with the actuator in normal position and turning moveto turn the wheel 22.

' From the foregoing, it will thus be seen that an extremely simple and compact vending machine has been devised which is absolutely foolproof irrespective of the manner in which it is manipulated and which is further provided with means which insures a delivery of the articles to be vended whenever a coin is inserted and the coin mechanism is operated.
